Blitz3D Docs -> Shr
Parameters:repetitions = number of shifts to make right
Description:This performs a left binary shift on the value the specified number of times. This basically is a faster method of dividing the value exponentially. By shifting right once, you are dividing the value by 2. By shifting right twice, you divide by 4, etc.
The usefulness of this command is basically faster math execution.

| Just noticed there is a typo. It says that shr performs a left binary shift. |
